III. Product Introduction:

The automatic dielectric loss tester is an instrument for measuring dielectric loss and capacitance. It is used under power frequency high voltage to measure the dielectric loss and capacitance of various high-voltage equipment such as insulating materials, insulating bushings, power cables, capacitors, transformers, and mutual inductors. It replaces the QSI high-voltage bridge and has the advantages of simple operation, Chinese display, printing, easy use, no conversion needed, built-in high voltage, strong anti-interference capability, and short test time. It is our company's third-generation intelligent dielectric loss tester.

Structure of the automatic dielectric loss tester: It is an integrated structure of voltage boosting and measurement, with output voltage adjustable in five gears from 2.5KV to 10KV to meet various needs. No external equipment is required during measurement. The wiring is similar to the QSI bridge but more convenient.

Principle of the automatic dielectric loss tester: The standard circuit consists of a built-in high-voltage stable standard capacitor and a standard resistor network. The computer collects the current amplitude and phase difference of the standard circuit and the test circuit in real time, and calculates the capacitance and dielectric loss of the tested object.
